Improve the handling of your classic AMC muscle car with ORP's Roller Spring Perches. Stock perches use rubber as the bushing between the perch and the perch-mounting shaft which greatly increases the effort required for your suspension to move. Our roller spring perches use sealed roller bearings to greatly reduce this resistance which improves ride quality, responsiveness to the road, and improved handling. * These roller perches are being sold by exchange only. The core charge is $100 if a usable exchange is not available. All core parts must be cleaned down to bare metal or an additional cleaning fee of $75 will be charged. Please allow 2-3 weeks for delivery. International Shipping is available. Please Contact Us for more information. AMC Roller Spring Perches Price: $199/pair *
